Comodo Antivirus security software contains many vulnerabilities that could put users at risk, according to Tenable Research researchers.
Tenable Research reports that the 18.104.22.16810 version of Comodo Antivirus and Comodo Antivirus Advanced contains multiple vulnerabilities.
David Wells carried out an in-depth check on these vulnerabilities and in a post to Medium blog, describes how security gaps could be used to allow a malicious user to escape the sandbox and gain system-level permissions. The researcher also published a PoC.
The first vulnerability, CVE-2019-3969, is a software issue in CmdAgent that allows attackers to bypass legitimate signature checks. Attackers are able to gain rights at the system level.
The second error is CVE-2019-3970, and it seems to be a very serious problem handling the Comodo software database. Tenable says the database can be stored in a protected folder on disk, but it is possible for any process with minimal permissions to modify the files in memory.
Another security gap is CVE-2019-3971, caused by an LCP port, cmdvrtLPCServerPort ..
Another is CVE-2019-3972, and is available at CmdAgent.exe.
The researcher also mentioned CVE-2019-3973, which affects security software only until the 22.214.171.12482 version.
Tenable's findings were reported to Comodo on April 17. By June, some of them had been confirmed, and the LPE error, according to Comodo, was "partly due to a Microsoft error."
We are currently expecting repairs from the security company. If you are using one of the applications mentioned above, it is advisable to use another, reliable one.
